My husband and I have been married for a year and a half and we have a wonderful relationship. Last April I took a new job where 95% of my co workers are male. I developed a flirty friendship with one (married) co worker and it quickly turned in to sexy texting and dirty talk. One night we met after work and made out like teenagers in his car. A few times we made out at work after hours. We always talked about meeting on our day off to fuck, but it never ended up happening. Our fling fizzled out. It was for the best. In the last few months I've developed a relationship with a different (single) co worker. We never got dirty in our messages, but the intent was implied. We'd take breaks together and flirt and 'accidentally' touch each other. Last week we were in a car watching the lot and he began to trace the length of my thigh and push my dress up further and further with each stroke. He finally reached my panties and started rubbing me over them. It didn't take long for him to push them aside and play with my pussy. Once I was good and wet he plunged two fingers deep inside me and fingered me like I haven't been fingered in ever. We were in plain sight if anyone had walked or driven by. The next day we made plans for lunch and instead of eating we went to his apartment and fucked like mad. He came three times and pulled out, but didn't do a very clean job the last time. This is the first time I've cheated on my husband and I should feel guilty, but instead I want more, more, more of my co worker. The thrill of all this excites me. My period is late.
